How does ransomware bypass security?

Ransomware bypasses security in several ways: zero-day variants with no signature evade antivirus; living-off-the-land techniques use legitimate tools to avoid behavioral detection; stolen credentials let attackers operate as trusted users; and intermittent or low-entropy encryption defeats anomaly- and entropy-based monitoring.

Crucially, most security layers inspect the perimeter, endpoint, or network — not the data itself. Elastio operates inside the data, performing deep file inspection so corruption is detected regardless of how the attacker bypassed the layers above it.
